Abstract

PURPOSE:To allow other party to reply to an incoming call even when an object called party cannot reply to the call by displaying the arrival of the call in a lamp of all key telephone sets of a relevant group when the call comes from a line wire. CONSTITUTION:When a call comes to a line wire 1, an incoming signal is sent to line wire unit 6, incoming call information of the line wire 1 is sent to a main control section 2, which uses a line wire/representative number storage section 53 to read a representative number 200 corresponding to the line wire 1 and a pointer storage section 56 reading an extension number 100 of a pointer storage section 53 of a group 1 is revised into 101. Then the main control section 2 reads a state storage section 55 of the extension number 100 and brings the state storage section 55 of the extension number 100 to the incoming call state when the number is idle. Then a lamp 1 of a lamp information storage section 54 corresponding to the line wire 1 is blinked, the main control section 2 starts an incoming call tone generating section 7 and a switch section 4 to send an incoming tone to the extension 100 and to blink the lamp 1 of the lamp information storage section 54 of extensions 101, 102 of the group 1. Thus, the call is displayed on other key telephone sets of the same group.

Description

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 2 is a diagram showing the configuration of the storage section in FIG. 1, and FIG. 3 is an example of processing of the main control section of this embodiment. This is a flowchart.

In FIG. 1, a button telephone main device 1 of this embodiment includes a button telephone unit 3 that accommodates a plurality of button telephones 10a to 10a with a lamp 11, an outside line unit 6 that accommodates a plurality of outside lines 1 to 3, and a button telephone A switch unit 4 that connects each other and the key telephones 10a to Ion and the outside lines 1 to 3 to form a communication path, an incoming call audio unit 7 that generates a ring tone, and the key telephones 10a to Ion are in a plurality of groups. The main control unit 2 controls the main unit 1 of the key telephone main device 1. .

In FIG. 2, the storage unit 5 in FIG. An extension number storage unit 52 that stores extension numbers, an outside line/representative number storage unit 53 that stores external lines 1 to 3 in correspondence with representative numbers, and a lamp that stores lamp information for each extension number. It is comprised of an information storage section 54, a status storage section 55 that stores the status of the extension, and a pointer storage section 56 that stores the extension number to receive the next call.

Next, the operation of this embodiment will be explained using FIG. 1, FIG. 2, and FIG. 3.

In advance, when starting up the key telephone W1, group 1 is set to ``200'' and group 2 is set to 2 in the representative number storage unit 51.
For group 3, a representative number of °°202" is set. Group 1 “100” is stored in the extension number storage unit 52;
"101", '102", group 2 "110'", "
111""112" Group 3 "120", 6
121" and "122", and the external line 1 is "200" and the external line 2 is "200" in the external line/representative number storage section 53.
01" and the representative number "202" for outside line 3. In the lamp information storage section 54, the lamps for outside lines 1 to 3 of all button telephones are set to "off," and in the status storage section 55, the main number "202" is set. Set the button telephone to "vacant" and pointer memory 5
6, group 1 is “100”, group 2 is “110”
, group 3 is set to "120".

First, when there is a callee on the outside line 1, an incoming call signal is sent to the outside line unit 6, and the incoming call information on the outside line 1 is sent to the main control unit 2 (step 21). The main control unit 2 includes an outside line/representative number storage unit 5
3 to read out the representative number "200" corresponding to the outside line 1 (step 22).

Step 23) Read the group number ``10'' from the representative number ``200.'' Step 24) Read the extension number ``100'' from the pointer storage section 53 of group 1. Step 24) Read the group number ``100'' from the pointer storage section 56 (Step 25).

Next, the main control unit 2 reads the status storage unit 55 of the extension number “100” (step 26), and if it is “vacant” (step 27), the status storage unit 5 of the extension number “100” is read.
5 is set to "incoming call" (step 28). Next, the lamp 1 in the lamp information storage unit 54 corresponding to the outside line 1 is set to "blink" (two steps). Next, the main control unit 2 activates the ring tone generator 7 and the switch unit 4 to send a ring tone to the extension “100” (step 30). If the status storage unit 55 is “other than empty”, the above process is performed for extension numbers “101′ and 102” in the same group 1. conduct.

When lamp 1 is pressed from a button telephone with extension "101°" that is not transmitting a ringtone, for example, lamp 1 press information is sent from button telephone unit 3 to main control section 2 (step 32). The main control unit 2, which has received the press information, controls the switch unit 4 to connect the communication path between the outside line 1 and the extension number "101" (step 33), and the extension numbers "100", "101", and '102'. The lamp 1 of the lamp information storage unit 54 of ``101'' is turned on (step 34), the status storage unit 55 of the extension number ``101'' is set to ``busy'' (step 35), and the switch 36).

You can also answer the call in the same way by pressing the lamp 1 of the key telephone with the extension number "100" that is ringing.

〔Effect of the invention〕

As explained above, when a call is received from an outside line, the present invention displays an incoming call on one key telephone in the group, and displays a lamp on all key telephones in the group to indicate that the call is incoming. This has the effect that even if the intended called party is unable to answer, someone else can answer the call, reducing the waiting time for the calling party.
